WILLIAM C. DILLON, OF FORT DODGE, IOWA, CURTISS J. TOAY, OF AVALON, PENNSYL- VANIA, WILLIAM H. TOAY, OFDES TvIOINES, AND ARCI-IIE HANEY, OF FORT DODGE, IOWA; SAID DILLON ASSIGNOR OF HIS ENTIRE RIGHT TO ALEXANDER B. RODER- IGK, OF DES MOINES, IOWA.

CASH-DRAWER BURGLAR ALARM.

VLaufrder.

To all 'whom it may concern:

Be it known that we, WILLIAM G. DILLoN, CURTISS J. ToAY, WILLIAM H. ToAY, and

' ARCHIE HANEY, citizens of the United States,

' will be given, parts being of simple, durable and inexpensive construction.

More particularly our invention relates to such a device that may readily and easily be installed upon the counter or cash drawers of a bank, and so adapted that when a certain portion of the money is removed from the cash drawer an alarm will be rendered at some distant point, notifying the people that hear the alarm that the money has been removed from the cash drawer.

Still another object is to provide a device, for containing currency that has a portion of the currency permanently therein for rendering an alarm device inoperative, while the remainder of the money or currency may be removed therefrom as would be the case in the ordinary banking business. The

device being so installed that anyone not' familiar therewith, and who had no authority to remove the money out of the drawer would, by the removal of the money give the alarm.

lVith these and other objects in view, our invention consists in the construction, arrangement and combination of the various parts of our device, whereby the objects contemplated are attained` as hereinafter more fully set forth, pointed out in our claims and illustrated in the accompanying drawings, in which:

Specification of Letters Patent. Patented Feb, 14, 1922,

Application filed January s, 1921.

Serial No. 434,574.

Figure 1 is a central, sectionalview, taken through our device as installed on a bank counter.

Figure 2 is a side elevation'of our device, parts being broken away to better illustrate the construction. y

Figure 3 is a top, plan view of the device showing the arm for holding` the device inoperative.

Figure 4 is a horizontal, sectional view, taken on the line t-l of Figure 1; and

Figure 5 is a modified form, showing the arm for holding the device inoperative.

In the accompanying drawings we have used the reference numeral 10 to indicate generally a bank counterror cashiers drawer, which is provided with the partition members 11 which are of the ordinary construe tion and which are used for separating the various denominations of currency.

It will be understoodthat our device is installed in each till or section so that removal of all of the currency of any one denomination will cause the alarm to ring.

The counter 10 is provided with an opening 12 and an annular recess in its upper surface 13. Our device which consists of a tubular shaped member or casing 111 is provided with a flange 15 on its upper edge, which is received in the recess 13, while the tubular member or casing 14 extends through the opening 12 and projects down below the under surface of the counter 10.

The flange 15 is provided with openings 16 for permitting screws 17 to be used for fastening the member 14 in position and against movement.

The lower end of the member 14 is screw threaded as at 1S for receiving the cap or closure member 19. The cap or closure member 19 is provided with a central opening 20 through which is extended the washer 21 which is of insulated materialV so that a Contact member 22 may extend through the washer and be insulated from the remainder of the device.

The contact member 22 1s provided with a screw threaded portion 23 upon which are guide devices or boltsf28 and 29.

The guide devices 28 and V29 extend through a slot30 inthe tubular shaped Vinember or casing lll. VVThe weight 27 is capable of vertical movement within the casing la and the movement thereof is limited by slot 30.

The'guide or 'bolt 29 lis pro-vided'with a nut 31 so that a wire 32 may be received between the head of the guideor bolt and the .nut r31. VA :bell33 is connected tothe wire. 32. :The wire'26 `is connected to ,a

source of energy 34 and then to the bell33 forcompletingthe wiring system.

.'Vhen ithe lower surface of the weight member rests upon the contact point 22 then arcomplete electrical circuit v.will be had and the bell will Vbe operated.

It will be understood that it is Our'intention 'to' only'fhave `the bell operate at certain timespthat .is whenlthebank is being robbed andi-the currency being removed from the cash drawerby someone `without authority todo so. Y 1 ln order jtoaholdgthe weight member out .of engagement with-the contact point V22 and for :breakingthe circuit we =have provided an arm `35 which is received in a groove ormedin the side ofthe weight 27 Vand is held liiredjthereto-by .means of the guide devices `28 and 29. Y

The upper end ofthe arm 35 is formed at right A.angles to -the portion of the device which restsagainst the weight 27 so as to orma,currencyy engaging member 36 which is yslightly spaced above the upper edge of the weight 27 and substantially .parallel therewith. Y v l Currency 37 'is placed in the drawers or sectionsll with a portion ofthe currency resting .below the lower. edge of the member v3.6.aiid above-.the upper edge of the weight 27 `as illustratedin Figure l vof the drawings. will .be seen that the placing. of the V(':urrencj-y in this position will prevent the weight member from `moving downwardly and thus causing it to be held in such .position that the electrical circuit will not be completed. VThe remainder of the currency willbe placed in the ordinaryway above the engagingmember 36, and can beV removed as inthe case of the ordinary.banlingbusiness will be seen that if someone not familiar with the alarm would attempt to rob the l b ankfandpull all otthevcurrencyout of the drawers or sections the weight 27 will then drop upon thercontact 22 and turn in. the alarm 4by ringing the bell 33.

as will be the case when-the oit substantially the same outline as i lt will also beV understood that thebell 33 may be located in some convenient place so that the person robbing the bank will not knowtliat he has Yturned in the'alarm'and that he has trapped himself 'l in ordinary switch may be used for clos-A ing the circuit when it is desiredV to repair or remove all the currency romtlie sections placed in the vault. Y v

The engagingmember 36 is Vprovided Awith an opening 37 so that an especially designed tool may be used for raising the weight Vmember after it has, once dropped.V f n Aln `Figure 5 of the drawings -we have shown-the. engaging member 36 circular and the opening within theqcasing A14C. f-

itlwill be seen-that our device .may readily and easily'be installed and lis .made of com# currency is oarativeli few )arts .which when onceA inj l J 7 stalled will zvery seldom become` out of order. When lthe device is installed, the ca pl9 is removed so as to permit :the casing `to'be slipped through the opening l2. The iweight 27 is then placed into the casing andthe guide devices installed in position. VV'The placing of the cap in thelower end ofthe casing .or tubular member 1 4 f completes the installation of our device. Y Y

Vlt lwill be seen .that wehave'provided a very effective cash drawer .burglar alarm Y.

which is very simple in rangement., A

Some changes vmay .beY made ,inthe conf struction and varrangemeiitof .the Vvarious construction and arvartsof our imjroved device without deL casing,guide devices iixed to ,saidfweight and extended through said slot, an armxed to said weight .and providedfwith. a portion spaced Vfrom the Vupper edgel of the ,Weight for receiving currency therebetween for Vholdingsaid weight up and whereby the removal of the currency will permit said weight to drop upon saidinsulated contact point Afor closing a circuit. 'l

2.. ln a device of the class Vdescribed a casing having a flange Yat its upper end and having its lower end screw threaded, aicap on said screw threaded end, an electricalV contact member fixed on said cap and-insulated therefrom, a second contact member slidably mounted in said casing, including a weight member having an arm fixed thereto, an en` gaging member formed on the upper end of said arm, a guide device for preventing ro- 5 tation of said Weight Within the casing, said guide device extending through the casing whereby an electrical Wire may be fastened thereto, the parts being so arranged that currency may be placed below said engaging 10 member for holding said second member out of engagement with said first contact member and when the currency is removed the contact members Will become engaged for completing an electrical circuit.
